LPS-41929 - On mobile, make permissions table easier to read

https://issues.liferay.com/browse/LPS-41929

Hey @jonmak08, I looked at the list of responsive tables and thought a pure css approach would be lighter than implementing a javascript plugin. The problem I ran into with a pure css approach is that the design patterns don't work in ie9 and below. In ie9 and below, I used overflow on the container method so the user can still scroll sideways to view the table.

I removed @include word-break(break-all) from line #49 because it looks like it was a fix for ee-6.1.x. Nate changed the mark up for Recent Downloads portlet in 6.2.
